ξέρω

Etymology: Derived from Ancient Greek 'ἐξεύρω' (exeúrō), meaning 'to find out, discover'. Over time, it evolved through Medieval Greek 'εξεύρω' (exévro) and eventually shortened to the modern form 'ξέρω' (xéro). The semantic shift from 'discovering' to 'knowing' reflects how knowledge often comes from discovery.
